As usual the government wants investors to keep forking out and creating jobs doing exploration, drilling, civil surveys, building infrastructure, doing environmental and heritage surveys, going through the permitting process etc.
Spend as much as you want but when it comes to the crunch for final project approval projects get knocked back and investors lose the lot.

Then the government teases and tempts investor cash down the next path of business development and milks that as much as it can before closing down that avenue too. Happening all over the world today. Job creation for the sake of it with no tangible economic good produced at the end.
It's ok, there is an infinite supply of cash anyway because the government is printing it and if anyone has any spare cash to invest in the National socialist economy, well then they can afford to lose it.
